Nshobora gukoresha ikibaho cya flex-flex mubushyuhe bwo hejuru?

Muri iyi nyandiko ya blog, tuzasesengura ibikwiye bya PCBs bigoye kugirango ubushyuhe bwo hejuru kandi tunatanga ubushishozi bugufasha gufata icyemezo kiboneye.

Iyo bigeze ku bikoresho bya elegitoronike n'ibigize, kimwe mu bintu by'ingenzi ugomba gusuzuma ni ubushyuhe bwabo bwo gukora. Ibidukikije bitandukanye bishobora kuzana ibibazo bitandukanye, kandi ubushyuhe bwo hejuru burashobora kuba busaba cyane.

Mu myaka yashize, habaye kwiyongera gushishikajwe no gukoresha PCBs igoye cyane. Izi PCB zitanga ibyiza byihariye nko kuzigama umwanya, kongera ubwizerwe hamwe nubuziranenge bwibimenyetso. Ariko, mbere yo kubishyira mubishushanyo byawe, birakenewe kumenya niba bishobora kwihanganira ubushyuhe bwo hejuru.

Sobanukirwa nuburyo bukomeye PCB imiterere

Ubwa mbere, reka tuganire muri make PCBs igoye nuburyo yubatswe.PCBs ya Rigid-flex ni imbaho ​​zumuzunguruko zihuza ibice byoroshye kandi byoroshye mubice bimwe. Bahuza ibyiza byubwoko bwombi bwa PCB, bigatuma bihinduka kandi bigashobora kuzuza ibisabwa byubushakashatsi.

Ubusanzwe rigid-flex PCB igizwe nibice byinshi byibikoresho bikomeye bihujwe nuburyo bworoshye.Ibice bikomeye bitanga imiterere ihamye, mugihe ibice byoroshye byemerera ikibaho kunama cyangwa kugundwa nkuko bikenewe. Iyi miterere idasanzwe ituma PCB ikoreshwa mubisabwa aho umwanya ari muto cyangwa ikibaho gikeneye guhuza nuburyo bwihariye.

Gisesengura ingaruka zubushyuhe bwo hejuru kuri PCB ikomeye

Ibintu byinshi biza gukina mugihe cyo gusuzuma ibikwiye PCBs zikoreshwa mugukoresha ubushyuhe bwinshi.Icyitonderwa cyingenzi ningaruka zubushyuhe kubikoresho bikoreshwa mubwubatsi bwa PCB.

Ibice bikaze byimbaho-flex ikozwe mubikoresho bisanzwe bikozwe mubikoresho nka FR-4, bizwiho guhagarara neza kwubushyuhe no kutagira umuriro.Ibi bikoresho birashobora kwihanganira ubushyuhe bugera kuri 130-140 ° C. Nyamara, igikoresho cyoroshye cya PCB gisanzwe gikozwe muri polyimide cyangwa ibikoresho bisa, bifite ubushyuhe buke.

Ibikoresho bya polyimide bikunze gukoreshwa muri PCB byoroshye birashobora kwihanganira ubushyuhe bugera kuri 250-300 ° C.Ariko rero, kumara igihe kinini uhura nubushyuhe bwo hejuru birashobora gutera kwangirika kwibintu, bikagabanya ubuzima rusange hamwe nimikorere ya PCB. Kubwibyo, ubushyuhe bwihariye busabwa mubushyuhe bwo hejuru bugomba gusuzumwa nibikoresho bikwiye byatoranijwe.

Ingamba zo Kugabanya Ibidukikije Ubushyuhe Bwinshi kubibaho byoroshye byacapwe byumuzunguruko

Mugihe PCBs idakomeye ishobora kugira aho igarukira mubushyuhe bukabije bwo hejuru, hariho ingamba nyinshi zo kugabanya ingaruka no kunoza imikorere.

1. Guhitamo ibikoresho:Guhitamo ibikoresho bifite ubushyuhe bwinshi kurwego rworoshye birashobora kuzamura cyane ubushyuhe rusange bwa PCB. Ibikoresho bya polyimide bifite imiterere yubushyuhe bwongerewe imbaraga, nka Tg yo hejuru (ubushyuhe bwikirahure), irashobora gukoreshwa mugice cyoroshye kugirango PCB yongere ubushobozi bwo guhangana nubushyuhe bwinshi.

2. Uburemere bw'umuringa n'ubugari bwa trike:Kongera uburemere bw'umuringa n'ubugari bwa trike kuri PCB bifasha gukwirakwiza ubushyuhe neza, bityo bikagabanya ibyago byo gushyuha cyane. Umuringa wimbitse hamwe nu muringa uremereye cyane, hamwe nuyobora imiyoboro minini, byongera ubushobozi bwubuyobozi bwo gukwirakwiza ubushyuhe.

3. Ikoranabuhanga ryo gucunga ubushyuhe:Gukoresha uburyo bwiza bwo gucunga neza ubushyuhe, nk'ubushyuhe, ubushyuhe bwo gukwirakwiza ubushyuhe, hamwe nuburyo bwo gukonjesha, bishobora gufasha kugumana ubushyuhe buringaniye bwa PCB muburyo bwemewe. Izi tekinoroji zifasha kuyobora ubushyuhe kure yibice bikomeye no kwirinda ibyangiritse.

4. Kwipimisha no kugenzura:Uburyo bukomeye bwo kwipimisha no kugenzura bugomba gukorwa kugirango PCBs igoye kwihanganira ibihe by'ubushyuhe bwo hejuru. Ikizamini cyamagare yubushyuhe, icyitegererezo cyikigereranyo, hamwe na software isesengura ubushyuhe birashobora gutanga ubushishozi mubikorwa bya PCB yubushyuhe kandi bigafasha kumenya aho bishobora guhangayikisha.

5. Ubuhanga bw'abatanga isoko:Nibyingenzi guhitamo uwizewe, ufite uburambe bwa PCB ufite ubuhanga mubushyuhe bwo hejuru. Utanga ubunararibonye arashobora kukuyobora muburyo bwo gutoranya ibikoresho, gutanga ibyifuzo byingamba zo kugabanya ibicuruzwa, no gutanga PCBs zujuje ubuziranenge zikomeye zujuje ibisabwa byihariye.

Mu mwanzuro

Mugihe PCBs idakomeye itanga ibyiza byinshi mubijyanye no kuzigama umwanya no kwizerwa, kuba bikwiranye nubushyuhe bwo hejuru biterwa no gusuzuma neza ibintu bitandukanye.Gusobanukirwa n'ingaruka z'ubushyuhe ku bikoresho byakoreshejwe, gukoresha ingamba zikwiye zo kugabanya ibicuruzwa, no gukorana n'abashoramari babimenyereye ni intambwe y'ingenzi mu kwemeza ishyirwa mu bikorwa rya PCB mu buryo bukabije.

Noneho, ikibaho gikomeye-flex gishobora gukoreshwa mubushyuhe bwo hejuru? Igisubizo kiri muburyo bwo gusuzuma neza ubushyuhe bwawe bukenewe, igishushanyo mbonera no guhitamo ibikoresho, hamwe no gukoresha uburyo bwiza bwo gucunga neza ubushyuhe.Urebye ibyo bintu, urashobora gufata icyemezo kibimenyeshejwe kandi ugakoresha inyungu zitangwa na PCBs zikomeye mugihe wizeye ko ibikoresho bya elegitoroniki byizewe mubushyuhe bwo hejuru.
